The Power Mac G4 is a series of personal computers designed, manufactured, and sold by Apple between 1999 and 2004. It uses the PowerPC G4 (PPC74xx) series of microprocessors.
[edit] Original models
The original Apple Power Mac G4 was introduced at the Seybold conference in San Francisco on 31 August 1999, with 400 MHz, 450 MHz and 500 MHz configurations available. In October 1999, Apple was forced to postpone the 500 MHz due to poor yield of the 500 MHz chips. In response, Apple “speed dumped” the processor speed in each configuration by 50 MHz but caused some controversy by not decreasing the price of the machines.
The early 400 MHz (later 350 MHz) PCI-based "Yikes!" version used a motherboard identical to the one used in Power Macintosh G3 (Blue & White) computers (minus the ADB port), in a "graphite" colored case and with the new PowerPC 7400 (G4) CPU. The higher-speed (Sawtooth) models used a greatly modified motherboard design with AGP 2x graphics (replacing the 66 MHz PCI slot). In December 1999, the entire Power Mac G4 line was updated to the AGP motherboard.
The machines featured DVD-ROM drives as standard. The 400 MHz and 450 MHz versions had 100 MB Zip drives as standard equipment, and as an option on the 350 MHz Sawtooth. This series had a 100 MHz System bus and four PC100 SDRAM slots for up to 2 GiB (2 GB[1])of RAM (1.5 GiB (1.5 GB[1]
